Patent JP-2000195653-A (JP)
Title: Induction heating device
Inventor: HIROTA MOTONARI
IPC: H05B6/12
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To provide a circuit reducing the loss of a switching element and reducing the noise of a cooling fan and power consumption by using an inverter circuit setting the inductance of a first coil in which a resonance current invariably flows during an oscillation period larger than the inductance of a second coil in which the resonance current partially flows during the oscillation period. SOLUTION: The current flowing in a switching element 13 becomes a resonance current, and the switching element 13 can be cut off when the current flowing in the switching element 13 is zero. No turn-off loss is generated as the loss of the switching element 13, only a normal loss is generated, and the loss of the switching element 13 can be sharply reduced. Since no turn-off loss is generated, the loss temperature characteristic becomes a nearly flat or negative characteristic, and an inverter circuit which is extremely stable thermally and easy for a cooling design can be obtained. The loss of the switching element 13 can be made nearly a half or below, thus power consumption can be reduced.
